Building a Secure Infrastructure for P2P Applications in Mobile Ad Hoc Networks

P2P and MANET share many similarities. Deploying P2P application in MANET faces many difficulties, especially when security consideration is incorporated. In this paper we propose a cluster-based architecture combined with a group key management scheme for mobile ad hoc network. A network is divided into clusters and each cluster has a leader called clusterhead. In order to address the problem of service registration and discovery better, we also propose a simple multicast-tree algorithm which organizes all clusterheads into trees based on each source clusterhead. The feasibility of this concept was verified by simulation results.
